In going from the
quark to the nucleon level one can follow a procedure analogous
for the determination of the nucleon spin from that of the quarks
[1]}, [2]}. The
matrix element at the nucleon level can be written as:
\(\mbox{me}_N=\langle N |\left( g_{aq}^0(\delta _0-\Delta s)+g_{as}\Delta s+g_{aq}^3\tau _{3}\delta _1\right)\sigma |N\rangle , \)
